7203L50P

Overview

The Renesas 7203L50P is an asynchronous FIFO memory device with a density of 18 kilobits, organized as 2K words by 9 bits. It features a unidirectional data bus architecture and operates within a core voltage range of 4.5 V to 5.5 V. The component provides a maximum access time of 50 ns and supports a clock frequency up to 15 MHz. It is housed in a 28-pin Plastic Dual In-line Package (PDIP) with a standard width of 0.600 inches.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• Unidirectional data flow architecture
• CMOS technology implementation

Applications

• Data buffering between disparate system speeds
• Interface bridging in digital signal processing chains
• Temporary storage in communication protocols

Procurement Notes

Verify the specific package variant, as the 'P' suffix denotes PDIP. Confirm RoHS compliance status, as many legacy variants are non-compliant. Check for discontinuation notices or end-of-life declarations from Renesas. Ensure availability of authorized distributors for genuine components. Validate pinout compatibility if replacing existing designs.

Selection Notes

Select this part for applications requiring simple asynchronous buffering with a 9-bit data width. Consider the 50 ns access speed against system timing requirements. Evaluate the PDIP package for through-hole mounting needs. Compare against faster alternatives like the 7203L12 series if higher throughput is necessary.

Part Context

This component belongs to the Renesas 7203/7208 family of asynchronous FIFOs. These devices are designed for high-speed data transfer applications where buffer memory is required between asynchronous systems. The family offers various access times and package options to suit different performance and form factor constraints.
